The aim of this thesis is to consider the knowledge and use of law by John of Salisbury, evaluating what he thought law should be, whence it originated and how it related to aspects of society, for example the institutions of the monarch and the church. For this purpose, the main evidence used will be Historia Pontificalis, Policraticus and the large corpus of letters. Chapter One is entitled Types of Law and gives an outline of the main types of law as John saw them. Chapter Two is entitled Canon Law. This chapter is devoted entirely to the study of John's knowledge and use of canon law. In this chapter, consideration will be made to what canon law John appears to have known and how John used this knowledge within his written work. Chapter Three, entitled King and Law, focuses upon John of Salisbury's opinion of the relationship between the monarch and the law. Chapter Four, Theory of Law: Church and King considers John's ideas on the relationship between church and monarch. Attention will also be paid to how he conveyed his ideas during the papal schism and the Becket dispute as well as John's ideas on judges. Chapter Five is entitled Law in Practice: Church and King, whereby analysis will be made of how John sees the monarch's involvement in issues such as church elections.

The reign of King Baldwin I (1100-1118) has thus far received little noteworthy attention by historians as the important pivotal period following the First Crusade conquest of Jerusalem in 1099. The two decades of his rule marked the extension of Latin conquests in the east, most notably by the conquest of the important coastal cities of Arsulf, Acre, Caesarea, Beirut and Sidon. These vital ports for the early Latin Kingdom of Jerusalem provided outlets to the sea for commerce, as well as safe harbors for incoming assistance from the west. Further, Baldwin led in the establishment of strong secular control over ecclesiastical authorities, and provided a model of administration for subsequent monarchs to follow until the loss of the kingdom in 1187. Baldwin's contributions to these developments are presented here in a bibliographical framework to illustrate both his important place in crusader historiography, as well as to gauge the significance of his memory in contemporary literature as a second Joshua archetype. The conquest of Jerusalem and the decades that followed were extraordinarily perilous for the western "colonial" transplants, and thus a Biblical precedent was sought as an explanation to the success of the crusaders. This thesis argues that Fulcher of Chartres, the chaplain and primary contemporary biographer of Baldwin I, saw a parallel with the Biblical figure of Joshua as beneficial to posterity. By the establishment of Baldwin's memory in such a context, Fulcher of Chartres encouraged further western support for the Latin Kingdom, and reveals the important trials that faced Jerusalem's first Latin king.

C'est à partir d'une historiographie de la ville de Chartres datant du XVIIe siècle et écrite par le chanoine Jean-Baptiste Souchet que nous avons élaboré la représentation du souverain idéalisée par son auteur. Et c'est en tentant de mettre en lumière cette dualité entre le pouvoir spirituel et le pouvoir temporel du roi, entre son statut de représentant de Dieu sur terre et son côté humain de suzerain, que nous avons trouvé une certaine forme de morale qui nous rappelait celle des humanistes Et cette morale, à noire étonnement, semble parfois avoir transcendé la religion pour refréner le pouvoir royal, prouvant que, pour certains penseurs de cette période, la légitimité divine ne pouvait à elle seule prévenir des abus de pouvoir. Le bon roi du chanoine Souchet, s'il devait être catholique, devait également posséder une morale qui F éloignerait de la faiblesse de sa condition humaine. / Québec Université Laval, Bibliothèque 2014

La notion, le statut et la question revisitée de la dispense canonique dans la tradition de l’Église latine, tels sont les trois temps que composent les réflexions proposées dans cette étude doctorale. Ces trois axes de recherche forment ce que nous appelons : la tradition canonique de la dispense dans l’Église catholique latine. Le premier temps de réflexion est celui sur la notion de dispensatio et d’οίκονομία. Cette réflexion explore la question des genèses de ces concepts qui, déjà au IIe siècle, sont employés par les pères de l’Église, Grecs et Latins, dans le contexte des communautés ecclésiales naissantes. Ces réflexions s’intéressent en même temps au domaine des premières doctrines autour de la pratique d’adoucissement de la rigueur des règles qui régissaient l’Église en ses débuts ; pratique à la fois spirituelle et pastorale. Le deuxième temps que propose cette dissertation doctorale s’inscrit dans l’apport scientifique et canonistique des collections canoniques du XIIe au XIVe siècle, celles notamment de Gratien et du ius novum après Gratien. À partir de XIIe siècle, le concept de dispense bénéfice d’une canonicité qui lui confère un statut canonique. Elle devient ainsi une institution du droit latin encore en gestation au milieu du Moyen-âge. La dispense est comprise dans un troisième temps comme une question revisitée au second concile du Vatican et par la codification contemporaine de 1983. Dans le cadre de l’aggiornamento proposé par Vatican II et dans une atmosphère apaisée, l’institution de la dispense retrouve l’idée originale d’une aide philanthropique, d’un acte de charité, d’une indulgence, d’une miséricorde. Elle est, pour les canonistes et pour les autorités ecclésiastiques, une institution de la guérison et du salut. / The notion, the status and the ‘revisited question’ of the canonical dispensation in the tradition of the Latin Church are the three axes of reflection proposed in this doctoral study. These three axes of research form what we call: the canonical tradition of dispensation in the Latin Catholic Church. The first period of reflection touches the notions of dispensatio and οίκονομία, and explores the question of the genesis of these concepts which were already in use in the second century by the Greek and Latin Fathers of the Church, in the context of the emerging ecclesial communities. These axes of reflection also concern the elaboration of the first doctrines relative to the practice of relaxing the rigor of the rules which governed the primitive Church both on a spiritual and pastoral level. The second axis of this doctoral dissertation focuses upon the scientific and canonistic contribution of canonical collections from the 12th to the 14th centuries, particularly those of Gratian and ius novum after Gratian. From the 12th century onwards, the concept of dispensation benefited from a “canonicity” that confers a canonical status. It thus becomes an institution of Latin Canonical law which was still being elaborated in the height of the Middle Ages. The question of dispensation is included in a third axis of reflection as ‘revisited’ during the second Vatican Council and by the contemporary codification of 1983. Within the framework of the aggiornamento proposed by Vatican II and in a calm atmosphere, the institution of dispensation finds once again it’s original meaning as a philanthropic aid, an act of charity, an indulgence, or a mercy. Indeed for canonists and for ecclesiastical authorities alike the dispensation is considered to be an institution of healing and of salvation.
